Artificial muscle for soft robotics: Low voltage, high hopes

Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult ...

Pressure-monitoring stockings to prevent wounds in diabetics

Diabetics often have little feeling in their feet and don't perceive the body's pressure or temperature signals there. This can result in unnoticed wounds that then develop into abscesses. Many diabetics have to have toes ...

Research team develops method to strengthen elastomers

Rethinking surface tension

(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.

Underwater propulsion from a 3D printer

Octopods, which are also known as octopuses or squid, are considered to be the most intelligent invertebrates. In fact, they have been referred to as the "sages of the sea". They are capable of learning; they can open tin ...
